Prognostic Significance of Sarcopenia in Patients with Unresectable Advanced Esophageal Cancer.

ABSTRACT: The prognostic significance of sarcopenia in unresectable advanced esophageal cancer remains unclear. Our study retrospectively evaluated 176 consecutive Japanese patients with esophageal squamous cell carcinoma who had been diagnosed with unresectable advanced cancer in Aichi Cancer Center Hospital between January 2007 and December 2014. Skeletal muscle mass was calculated from abdominal computed tomography (CT) scans before treatment, and patients were divided into sarcopenic and non-sarcopenic groups. Sarcopenia was present in 101 patients (57.4%). Eighty-two patients in the sarcopenic group and 63 patients in the non-sarcopenic group died during follow-up (mean: 20.3 months). The overall survival (OS) rate was significantly lower in the sarcopenic group compared to the non-sarcopenic group (2-year OS: 9.8% vs. 23.7%, p < 0.01). Cox regression analysis revealed only pretreatment sarcopenia as an independent prognostic factor (hazard ratio (HR): 1.48, 95% confidence interval (CI): 1.04-2.10, p = 0.03). In the sarcopenic group, withdrawn cases, for whom the planned treatment was discontinued for some reason, showed a significantly lower OS rate compared to complete cases (1-year OS: 11.0% vs. 59.9%, p < 0.01). The most common reason for discontinuation was aspiration pneumonia (64.5%). Presence of sarcopenia was an independent prognostic factor for unresectable advanced esophageal cancer. Identifying the presence of sarcopenia prior to treatment may improve the prognosis.

Project description:Background: Sarcopenia, systemic inflammation, and low muscularity significantly impact the survival of cancer patients. However, few studies have investigated how sarcopenia and systemic inflammation affect the prognosis of biliary tract cancer with distant metastasis. In this study, we investigated the association between sarcopenia with systemic inflammation and prognosis of metastatic biliary tract cancer. Materials and Methods: Data collected from 353 metastatic biliary tract cancer patients from 2007 to 2016 were analyzed. To evaluate the skeletal muscle mass, computed tomography images at the upper level of the third lumbar vertebra (L3) were used. Sarcopenia was defined using the Japan Society of Hepatology guideline; L3 muscle index <42 cm2/m2 for male and <38 cm2/m2 for female patients. Systemic inflammation was evaluated using the neutrophil lymphocyte ratio (NLR). Patients with NLR > 3 were categorized into the inflammatory category. The overall survival (OS) and progression free survival (PFS) were analyzed. Subgroup analysis was performed on those who received gemcitabine/cisplatin (GP) chemotherapy and depending on the presence of sarcopenia and inflammation. Results: Patients with sarcopenia showed lesser 1-year OS than those without (25.5 vs. 38.2%, p = 0.019). The patients with high NLR (NLR > 3) were associated with a shorter OS than were those with a low NLR (NLR ≤ 3) (21.0 vs. 52.8%, p < 0.001). Based on these results, we categorized the patients into three groups; sarcopenia accompanied by high NLR, no sarcopenia and low NLR, and either sarcopenia or high NLR. The OS of patients was well-stratified according to this grouping (1-year OS; 18.3 vs. 30.3 vs. 55.8%, p < 0.001). Concordant with OS results, the PFS was well-stratified based on the presence of either sarcopenia or high NLR (Sarcopenia; 9.5 vs. 19.4%, p < 0.001, NLR; 10.0 vs. 23.4%, p < 0.001). The PFS was significantly associated with high NLR and sarcopenia (1-year PFS; 7.8 vs. 13.0 vs. 27.9%, p < 0.001). Conclusion: Sarcopenia with inflammation was associated with inferior OS and PFS. In addition, sarcopenia accompanied by inflammation was associated with poor prognosis. Conservative treatments such as nutritional support, exercise, and pharmacologic intervention could help metastatic biliary tract cancer patients to overcome sarcopenia and the inflammatory status.

Project description:BackgroundPreoperative sarcopenia is associated with a poor long-term prognosis in patients with gastric cancer (GC). Most GC patients rapidly lose muscle mass after gastrectomy. This retrospective cohort study analysed the effect of postoperative muscle loss and surgery-induced sarcopenia on the long-term outcomes of patients with GC.MethodsPreoperative and postoperative 1 year abdominal computed tomography scans were available for 1801 GC patients who underwent curative gastrectomy between January 2009 and December 2013 at Seoul National University Bundang Hospital. The patients were categorized into normal, presarcopenia, and sarcopenia groups according to the skeletal muscle index (SMI) measured on computed tomography scans. Patients who were not sarcopenic prior to gastrectomy but became sarcopenic after surgery were defined as the surgery-induced sarcopenia group.ResultsThere were 1227 men and 574 women included in the study. The mean age of the patients was 59.5 ± 12.3 years. Multivariable Cox-regression analyses showed that preoperative SMI was not associated with overall survival (OS). However, postoperative sarcopenia was associated with significantly worse OS only in men [hazard ratio (HR), 1.75; 95% confidence interval (CI), 1.08-2.85]. SMI loss was an independent risk factor for OS in the entire cohort and in men (HR, 1.01; 95% CI, 1.00-1.02, for the entire cohort; HR, 1.02; 95% CI, 1.01-1.04, for men). The surgery-induced sarcopenia group was associated with significantly higher mortality (HR, 1.84; 95% CI, 1.16-2.90, for the cohort; HR, 2.73; 95% CI, 1.54-4.82, for men), although SMI loss and surgery-induced sarcopenia were not risk factors in women. Similar results were obtained for relapse-free survival.ConclusionsPostoperative muscle mass loss and surgery-induced sarcopenia are prognostic factors for survival in patients with GC. Impact of postoperative muscle mass loss and surgery-induced sarcopenia on survival outcomes is dependent on the sex.

Project description:Abstract Background and Aim Polypharmacy and sarcopenia are increasing public health problems worldwide. However, data on the prevalence, association, and prognostic significance of polypharmacy and sarcopenia in patients with liver cirrhosis are limited. Methods Polypharmacy and sarcopenia were assessed in 239 patients with liver cirrhosis. Polypharmacy was defined as the daily use of six or more medications, and sarcopenia was diagnosed based on muscle strength and mass evaluated on computed tomography. The association between polypharmacy and sarcopenia and their effects on mortality were analyzed using logistic regression and Cox proportional hazards models. Results Among the 239 patients, 52% were men, the median age was 68 years, and the number of medications used per patient was 6. Further, 53% and 29% patients had polypharmacy and sarcopenia, respectively. The number of medications used and the prevalence of sarcopenia increased with age. Patients with polypharmacy and sarcopenia had similar characteristics, such as older age, increased medication use, advanced liver disease, and decreased muscle strength and mass. After adjusting for confounders, polypharmacy was significantly associated with sarcopenia (odds ratio, 2.11; 95% confidence interval [CI], 1.07–4.17). During the median follow‐up of 2.2 years, 62 (26%) patients died. Polypharmacy (hazard ratio [HR], 1.83; 95% CI, 1.01–3.37) and sarcopenia (HR, 2.00; 95% CI, 1.12–3.50) independently predicted mortality. The prognostic significance of polypharmacy was more prominent in older adults than in younger adults (HR, 2.31; 95% CI, 1.01–5.67). Conclusion Polypharmacy and sarcopenia are interrelated and associated with poor prognosis in patients with cirrhosis. Further large, prospective, population‐based studies are required to validate these findings. Polypharmacy and sarcopenia are increasing public health problems worldwide, but the prevalence, association, and prognostic significance of polypharmacy and sarcopenia in patients with liver cirrhosis remain unclear. Our data indicate that polypharmacy and sarcopenia are common, interconnected, and associated with mortality in patients with cirrhosis.

Project description:BACKGROUNDS:The relationship between sarcopenia, characterized by loss of muscle mass and strength, and survival outcomes of esophageal cancer is controversial. This study aimed to assess the effect of sarcopenia and skeletal muscle loss on overall survival (OS) and recurrence-free survival (RFS) of esophageal cancer patients. METHODS:We retrospectively collected the medical records of 248 male patients diagnosed with squamous cell esophageal cancer and who underwent neoadjuvant chemoradiotherapy (NACRT) followed by surgery. We measured the cross-sectional area of the skeletal muscle at the L3 vertebra level using computed tomography images and calculated the skeletal muscle index (SMI). Sarcopenia was defined as SMI <52.4 cm2/m2, and excessive muscle loss was defined as SMI change <-10.0%/50 days during NACRT. Moreover, laboratory test results, such as albumin, prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) before and after NACRT, were collected. RESULTS:In the univariable Cox analysis, pre- (p = 0.689) and post-radiotherapy (RT) sarcopenia (p = 0.669) were not associated with OS. However, excessive muscle loss had a significant association with OS in both the univariable and multivariable analyses (all p = 0.001). Excessive muscle loss was also related to RFS in both the univariable (p = 0.011) and multivariable (p = 0.022) Cox analysis. Patients with excessive muscle loss had significantly lower levels of post-RT albumin (p < 0.001) and PNI (p < 0.001), higher levels of post-RT NLR (p = 0.031) and PLR (p = 0.071), larger decrease in albumin (p < 0.001) and PNI (p < 0.001) after NACRT, and larger increase in NLR (p = 0.051) and PLR (p = 0.088) after NACRT than in those with non-excessive muscle loss. CONCLUSION:Excessive muscle loss rather than pre- and post-RT sarcopenia was a significant prognostic factor for OS and RFS, and it was also related to nutritional and inflammatory markers.
